[0014] As a preferred technical solution of the present application, a material discharge trough is also provided on the top of the workbench, and a material collection box cooperating with the material discharge trough is provided on the bottom of the workbench.

[0015] A method for testing the strength and compressive strength of a foamed ceramic plate comprises the following steps:

[0016] S1: Place the foamed ceramic plate to be tested on the top of the workbench, start the first driving cylinder to drive the first connecting plate connected to its output end to move downward along the first sliding rod, and when it moves downward, it will drive the L-shaped connecting plate connected to the side wall of the first connecting plate to move downward with it, thereby driving one end of the first connecting rod group connected to the L-shaped connecting plate to move downward. Since the other end of the first connecting rod group is rotatably connected to the clamping plate, when the L-shaped connecting plate moves downward, the clamping plate will be driven to slide along the sliding groove toward the middle of the workbench through the first connecting rod group, the sliding groove opened on the workbench and the second sliding rod set at the bottom of the clamping plate, thereby clamping and fixing the foamed ceramic plate placed on the top of the workbench, thereby improving its stability during strength and pressure resistance testing, avoiding the foamed ceramic plate from falling off and sliding during testing, and ensuring the accuracy of testing;

[0017] S2: When the clamping plate moves along the slide groove toward the middle part of the workbench, it will also drive the first fixed seat connected to its bottom to move along the second slide rod toward the middle part of the workbench. At this time, it will drive the second connecting plate connected to the side wall of the first fixing seat and the end of the second connecting rod group connected to the second connecting plate to move along the second slide rod toward the middle part of the workbench. When the second connecting rod group moves toward the middle part of the workbench, the second guard plate connected to the second connecting rod group will be driven to move upward along the groove through the groove set on the workbench, and cooperate with the first guard plate to form an enclosed enclosure. Therefore, when the foamed ceramic plate cracks during the strength and compression test, it can play a good protective effect, avoid the splashing of the cracked slag and debris and cause personal injury to the operator, and improve the safety performance.

[0018] S3: Start the second driving cylinder to drive the fixed plate connected to its output end to move downward. When the second fixed plate moves downward, it will drive the detector and the positioning component to move downward. The height of the positioning component is less than the height of the detector. Therefore, when the second fixed plate drives the detector and the positioning component to move downward, the positioning component first contacts the foamed ceramic plate to be detected. At this time, the foamed ceramic plate to be detected can be further limited and fixed, thereby improving its stability during strength and pressure resistance testing, avoiding the foamed ceramic plate from falling off and sliding during testing, and improving the accuracy of testing. After the positioning component further fixes and limits the foamed ceramic plate to be detected, the detector contacts the foamed ceramic plate, and the length of the second driving cylinder extended is controlled to cooperate with the detector to conveniently perform accurate strength and pressure resistance testing on it.

[0019] S4: After the detection is completed, first start the second driving cylinder to retract, thereby driving the detector and the positioning assembly to move upward away from the foamed ceramic plate to be detected, and then start the first driving cylinder to move upward, which will drive the detector and the positioning assembly to move upward away from the foamed ceramic plate. At the same time, the upward movement of the first driving cylinder will also drive the L-shaped connecting plate connected to it to move upward, and the first connecting rod group provided in cooperation will drive the clamping plate to move toward the two ends of the workbench to release the clamping of the foamed ceramic plate. When the clamping plate moves toward the two ends of the workbench, the second connecting rod group provided will drive the second guard plate to move downward along the slot. At this time, the foamed ceramic plate after the detection can be conveniently moved away, and at the same time, it is convenient to place the next foamed ceramic plate and perform strength and compression tests;

[0020] S5: When the foamed ceramic plate under inspection is broken, the second driving cylinder and the first driving cylinder are started to drive the detector and the positioning assembly to move upward and away from the workbench, the clamping plate moves toward both ends of the workbench, and the second guard plate moves downward. Then, the broken foamed ceramic plates on the workbench can be cleaned out of the workbench through the set discharge chute, and the broken foamed ceramic plates can be collected uniformly through the set collection box to facilitate subsequent cleaning.

[0021] Compared with the prior art, the present invention provides a foamed ceramic plate strength and compression testing device, which has the following beneficial effects:

[0022] 1. The foamed ceramic plate strength and compression testing device can drive the tester away from the work surface through the provided lifting assembly, so as to facilitate placing the foamed ceramic plate to be tested on the work surface, and at the same time facilitate moving the foamed ceramic plate after testing away;

The foamed ceramic plate strength and compression testing device can conveniently and quickly fix the foamed ceramic plate to be tested through the provided lifting group, linkage assembly and clamping assembly, and can perform secondary fixed position limiting on the foamed ceramic plate in cooperation with the provided positioning assembly, which can effectively prevent the foamed ceramic plate from moving and falling during the test and affecting the test effect;

[0024] 3. The foamed ceramic board strength and compression resistance testing device, through the coordination of the lifting group, linkage assembly, clamping assembly, adjustment assembly and protection assembly, can not only provide good protection for operators during the testing process, but also facilitate the placement and removal of the foamed ceramic board.

The discharge trough 101 and the collecting box 102 can conveniently remove the broken plates during the inspection.

[0048] Specifically, when the present foamed ceramic plate strength compression test device is used: first, the foamed ceramic plate to be tested is placed on the top of the workbench 100, and the first driving cylinder 302 is started to drive the first connecting plate 304 connected to its output end to move downward along the first sliding rod 303. When it moves downward, it will drive the L-shaped connecting plate 801 connected to the side wall of the first connecting plate 304 to move downward with it, and then drive one end of the first connecting rod group 802 connected to the L-shaped connecting plate 801 to move downward. 601 is connected in rotation, and when the L-shaped connecting plate 801 moves downward, the first connecting rod group 802, the slide groove 605 provided on the workbench 100 and the second slide rod 604 provided at the bottom of the clamping plate 601 will drive the clamping plate 601 to slide along the slide groove 605 toward the middle of the workbench 100, thereby clamping and fixing the foamed ceramic plate placed on the top of the workbench 100, improving its stability during strength and compression testing, avoiding the foamed ceramic plate from falling off and sliding during testing, and ensuring the accuracy of testing;

[0049] When the clamping plate 601 moves along the slide groove 605 toward the middle part of the workbench 100, it will also drive the first fixed seat 602 connected to its bottom to move along the second slide bar 604 toward the middle part of the workbench 100. At this time, the second connecting plate 901 connected to the side wall of the first fixed seat 602 and the end of the second connecting rod group 902 connected to the second connecting plate 901 will be driven to move along the second slide bar 604 toward the middle part of the workbench 100. When the second connecting rod group 902 moves toward the middle part of the workbench 100, the second guard plate 702 connected to the second connecting rod group 902 will be driven to move upward along the groove through the groove set on the workbench 100, and cooperate with the first guard plate 701 to form a closed enclosure. Therefore, when the foamed ceramic plate cracks during the strength and compression test, it can play a good protective effect, avoid the splashing of the cracked debris and fragments and cause personal injury to the operator, and improve the safety performance.

[0050] Start the second driving cylinder 401 to drive the fixed plate 402 connected to its output end to move downward. When the second fixing plate 402 moves downward, it will drive the detector 200 and the positioning assembly 500 to move downward. The height of the positioning assembly 500 is less than the height of the detector 200. Therefore, when the second fixing plate 402 drives the detector 200 and the positioning assembly 500 to move downward, the positioning assembly 500 first contacts the foamed ceramic plate to be detected. At this time, the foamed ceramic plate to be detected can be further limited and fixed, thereby improving its stability during strength and pressure resistance testing, avoiding the foamed ceramic plate from falling off and sliding during testing, and improving the accuracy of testing. After the positioning assembly 500 further fixes and limits the foamed ceramic plate to be detected, the detector 200 contacts the foamed ceramic plate, and the length of the second driving cylinder 401 extended is controlled to cooperate with the detector 200 to conveniently perform accurate strength and pressure resistance testing on it.

[0051] After the detection is completed, first start the second driving cylinder 401 to retract, thereby driving the detector 200 and the positioning assembly 500 to move upward and away from the foamed ceramic plate to be detected, and then start the first driving cylinder 302 to move upward, which will drive the detector 200 and the positioning assembly 500 to move upward and away from the foamed ceramic plate. At the same time, the upward movement of the first driving cylinder 302 will also drive the L-shaped connecting plate 801 connected thereto to move upward, and the first connecting rod group 802 provided in cooperation drives the clamping plate 601 to move toward the two ends of the workbench 100 to release the clamping of the foamed ceramic plate. When the clamping plate 601 moves toward the two ends of the workbench 100, the second connecting rod group 902 provided will drive the second guard plate 702 to move downward along the slot. At this time, the foamed ceramic plate after the detection can be conveniently moved away, and at the same time, it is convenient to place the next foamed ceramic plate and perform strength and compression tests.

[0052] When the foamed ceramic plate being tested is broken, the second driving cylinder 401 and the first driving cylinder 302 are started to drive the detector 200 and the positioning assembly 500 to move upward and away from the workbench 100, the clamping plate 601 moves toward both ends of the workbench 100, and the second guard plate 702 moves downward. Then, the broken foamed ceramic plates on the workbench 100 can be cleaned out of the workbench 100 through the set discharge trough 101, and the broken foamed ceramic plates can be collected uniformly through the set collection box 102 to facilitate subsequent cleaning.

4. A method for testing the strength and compressive strength of a foamed ceramic plate, characterized in that: Using the foamed ceramic board strength compression testing device as claimed in claim 2, the testing method comprises the following steps: S1: Place the foamed ceramic plate to be tested on the top of the workbench (100), start the first driving cylinder (302) to drive the first connecting plate (304) connected to its output end to move downward along the first sliding rod (303), and when it moves downward, it will drive the L-shaped connecting plate (801) connected to the side wall of the first connecting plate (304) to move downward with it, thereby driving one end of the first connecting rod group (802) connected to the L-shaped connecting plate (801) to move downward. Due to the rotation of the other end of the first connecting rod group (802) and the clamping plate (601), When the L-shaped connecting plate (801) moves downward, the first connecting rod group (802), the slide groove (605) provided on the workbench (100), and the second slide rod (604) provided at the bottom of the clamping plate (601) will drive the clamping plate (601) to slide along the slide groove (605) toward the middle of the workbench (100), thereby clamping and fixing the foamed ceramic plate placed on the top of the workbench (100), thereby improving its stability during strength and compression testing, and preventing the foamed ceramic plate from falling off and sliding during testing; S2: When the clamping plate (601) moves along the slide groove (605) toward the middle of the workbench (100), it will also drive the first fixed seat (602) connected to the bottom thereof to move along the second slide bar (604) toward the middle of the workbench (100), and at this time, the second connecting plate (901) connected to the side wall of the first fixed seat (602) and the end of the second connecting rod group (902) connected to the second connecting plate (901) will be driven along the second slide bar (604) toward the middle of the workbench (100). When the second connecting rod group (902) moves toward the middle part of the workbench (100), the second guard plate (702) connected to the second connecting rod group (902) is driven to move upward along the groove through the groove provided on the workbench (100), and cooperates with the first guard plate (701) to form a closed enclosure, so that when the foamed ceramic plate is cracked during the strength and compression test, it can play a good protective effect and prevent the cracked debris from splashing and causing personal injury to the operator; S3: Start the second driving cylinder (401) to drive the fixed plate (402) connected to its output end to move downward. When the fixed plate (402) moves downward, it will drive the detector (200) and the positioning assembly (500) to move downward. The height of the positioning assembly (500) is less than the height of the detector (200). Therefore, when the fixed plate (402) drives the detector (200) and the positioning assembly (500) to move downward, the positioning assembly (500) first contacts the foamed ceramic plate to be detected. At this time, the foamed ceramic plate to be detected can be further limited and fixed, thereby improving its stability during strength and pressure resistance testing, avoiding the foamed ceramic plate from falling off and sliding during testing, and improving the accuracy of testing. After the positioning assembly (500) further fixes and limits the foamed ceramic plate to be detected, the detector (200) contacts the foamed ceramic plate, and the length of the second driving cylinder (401) is controlled to cooperate with the detector (200) to conveniently perform accurate strength and pressure resistance testing on it; S4: After the detection is completed, the second driving cylinder (401) is started to retract, thereby driving the detector (200) and the positioning assembly (500) to move upward away from the foamed ceramic plate to be detected, and then the first driving cylinder (302) is started to move upward, at which time the detector (200) and the positioning assembly (500) are driven to move upward away from the foamed ceramic plate; at the same time, the upward movement of the first driving cylinder (302) also drives the L-shaped connecting plate (801) connected thereto to move upward, and the first connecting rod group (802) provided in cooperation drives the clamping plate (601) to move toward the two ends of the workbench (100) to release the clamping fixation of the foamed ceramic plate. When the clamping plate (601) moves toward the two ends of the workbench (100), the second connecting rod group (902) provided will drive the second guard plate (702) to move downward along the slot, so that the foamed ceramic plate after the detection can be conveniently moved away, and at the same time, it is convenient to place the next foamed ceramic plate and perform strength and compression test; S5: When the foamed ceramic plate being tested is broken, the second driving cylinder (401) and the first driving cylinder (302) are similarly started to drive the detector (200) and the positioning assembly (500) to move upward away from the workbench (100), the clamping plate (601) moves toward the two ends of the workbench (100), and the second guard plate (702) moves downward. Then, the broken foamed ceramic plate on the workbench (100) is cleaned out of the workbench (100) through the set discharge trough (101), and the broken foamed ceramic plate can be uniformly collected through the set collection box (102).
